Subacute clinical features after arthroscopy surgical reconstruction of complete anterior cruciate ligament rupture: A case-control study

Abstract

Objective: The purpose of this study was to describe the clinical features in the subacute phase after surgical reconstruction of complete anterior cruciate ligament rupture (ACLR) with respect to healthy participants. Methods: A case-control observational study was performed. A total sample of 80 participants was recruited from an outpatient clinic and divided into case (n = 40 patients after ACLR reconstruction in subacute phase) and control (n = 40 healthy participants) groups. Outcomes, including pain intensity, range of motion (ROM), stability, and functionality were assessed by the visual analogue scale, universal goniometer, the Star Excursion Balance Test, and the Western Ontario and McMaster Universities Osteoarthritis Index, respectively. Results: There were no statistically significant differences (P > .05) for sex, side, age, and body mass index between patients with ACLR after reconstruction surgery and healthy participants. Statistically significant differences (P < .001) with a large effect size (Rosenthal r) from -0.86 to -0.93 were shown for ROM (median ± interquartile range [IQR], -70.00° ± 10.00°) and Star Excursion Balance Test (mean ± standard deviation, -38.31 cm ± 4.52 cm) reduction, as well as higher visual analogue scale (median ± IQR, 7.00 ± 1.00) and Western Ontario and McMaster Universities Osteoarthritis Index (median ± IQR, 68.77 ± 6.29) scores in favor of the ACLR reconstructed group, with respect to the healthy control group. Conclusions: Measurable clinical differences of functionality, stability, and ROM should be considered during the evaluation of patients at a subacute period after complete ACLR reconstruction surgery with respect to healthy matched controls.
